Remarks

A compact patricia trie that uses strings as keys.

This data structure can be very space-efficient when asked to store a large numbers of keys with common prefixes; maximum efficiency is achieved when the associated values are all (or almost all) null.

Template Parameters

TValue Type of value associated with each key.

Member Function Documentation

bool Loyc.Collections.CPStringTrie< TValue >.TryAdd	(	string	key,
		TValue	value
	)

inline

Adds the specified key-value pair only if the specified key is not already present in the trie.

Returns: Returns true if the key-value pair was added or false if the key already existed. In the false case, the trie is not modified.

bool Loyc.Collections.CPStringTrie< TValue >.TryAdd	(	string	key,
		ref TValue	value
	)

inline

Adds the specified key-value pair only if the specified key is not already present in the trie.

Parameters

value On entry, value specifies the value to associate with the specified key, but if the key already exists, value is changed to the value associated with the existing key.

Returns: Returns true if the key-value pair was added or false if the key already existed. In the false case, the trie is not modified.
